The two side surfaces 31 are disposed opposite each other and parallel to the plane in which the X-direction and the Z-direction lie. Thus, when the heating element 40 is energized, it heats and atomizes the liquid matrix at the side surface 31, and the aerosol formed by the atomization can enter the smoke discharge pipe 11 through the ventilation groove 23 and the communication groove 25 in order along the two R3 routes shown in fig. 4.

When the capillary element 30 is accommodated in the accommodating groove 22, the upper surface 32 can face the liquid channel 21, and the liquid channel 21 is blocked by the upper surface 32, so that the liquid matrix only enters the capillary element 30 from the upper surface 32 through the internal pores.
The heating element 40 includes a first connection end 41, a second connection end 42, and a heating portion 43 bent and extending between the first connection end 41 and the second connection end 42. The two first connection ends 41 of the two heating elements 40 are connected by a first connection portion 44 provided on the lower surface 33, and the two second connection ends 42 of the two heating elements 40 are connected by a second connection portion 45 provided on the lower surface 33. The heating element 40 and the first and second connection portions 44 and 45 may be integrally printed on the capillary element 30 by a film printing technique.

The heat generating portion 43 may be a sheet structure having a plurality of openings, or may be a meander line structure.
In an alternative embodiment, as shown in connection with fig. 5 and 9, fig. 9 is a perspective view of the base 50 of the atomizer 100 of fig. 5; the base 50 may be snap-fit with the slot 15 on the housing 10, for example, by a latch 53, for retaining the bracket 20 within the housing 10. For example, referring to fig. 6, the inner wall of the housing 10 may be provided with a plurality of ribs 16, and lower ends of the ribs 16 remote from the nozzle portion 14 are adapted to abut against upper ends of the brackets 20; referring again to fig. 9, the base 50 includes an upper end surface 54 and an intermediate support surface 55; as shown in connection with fig. 7, the upper end surface 54 and the intermediate support surface 55 of the base 50 serve to support the main body lower end surface 20b and the bracket lower end surface 29 of the bracket 20. The main body lower end surface 20b may be a lower end surface of the bracket main body 20a, and the bracket lower end surface 29 may be a lower end surface of the bracket 20. In addition, the base 50 may include a slot 59, and a lower end surface of the housing 10 remote from the nozzle portion 14 may be further provided with an insert 17; when assembled, the insert 17 may be inserted into the slot 59. In this way, the bracket 20 can be securely held within the housing 10.
In an alternative embodiment, as shown in connection with fig. 7, the bracket 20 includes an annular surrounding portion 28, and the ventilation slots 23 extend to the inside of the annular surrounding portion 28. The annular surrounding portion 28 may extend away from the mouthpiece portion 14 from the holder body 20 a. As shown in fig. 9, the base 50 includes an annular insertion portion 51, and two grooves 52 are formed at the top end of the annular insertion portion 51; the annular insertion portion 51 may extend from the base body 50a of the base 50 toward the bracket 20. The upper surface of the base body 50a forms the intermediate support surface 55, and the intermediate support surface 55 surrounds the annular insertion portion 51. The recess 52 may be recessed from the upper end surface 54. The base 50 may include one or more intake pillars 56, with airflow passages within the intake pillars 56 for introducing outside air into an interior space 57 of the base 50.
As shown in fig. 3, 4, 7 and 9, in the assembled structure, the annular insertion portion 51 is inserted in the annular surrounding portion 28, and the two grooves 52 communicate with the two ventilation grooves 23, respectively. Thus, when the user sucks the mouthpiece portion 14 of the nebulizer 100, the air pressure in the nebulizer 100 decreases, so that the outside air enters the internal space 57 of the base 50 through the air inlet column 56 along the R1 route shown in fig. 3; air within interior space 57 may then enter vent groove 23 via groove 52 along the path R2 shown in fig. 4. Accordingly, in the whole atomizer 100, external air sequentially enters the ventilation groove 23 along the route R1 and the route R2, and aerosol formed by heating and atomizing the liquid matrix when the heating element 40 is electrified and works in the ventilation groove 23 is carried into the smoke exhaust pipe 11 along the route R3, and is further discharged by the suction nozzle part 14 for being sucked by a user.
